Network POE issue

So the original tester that you used didn't tell you that the pairs were mis-wired?
 
Thank you all for your suggestions and help with this endeavor!  Your help was sincerely appreciated.
 
Yup; the cheapo $10 ones just have LEDs.  One of the two I have has red and green and blink in order top to bottom. 
 
The new "el cheapo" tester (from the manual) features:
 
1 - wiring errors for 5e,6e, telephone and coaxial cable
2 - open circuit, short circuit, jumper wire, reverse connection or cross-talk interference
3 - locating a wiring or connection error
4 - measure cable length and determine distance of open or short circuit
5 - dynamically calibrate cable length (97% accuracy)
6 - big screen (easy to read outside).
7 - measure length and pair without "far end recognizer) one was included.
8 - far end recognizer with prompting voice (it chirps)
 
Personally here my issues were:
 
1 - new patch panel which is not illuminated.  The original one has two lamps above it which do light up the area (cans et al)
2 - the cables' pair colors appear to be tinted rather than solid colors which cause issues for me with red, green and orange pairs.
 
Typically I utilize the patch panel and keystone jacks.  I rarely put RJ-45 ends (unless making patch cables).  That said I put two extended test cables outside by my deck to test POE cams.  Both were mis wired.  I am surprised that they worked.  I did order a "few" new patch cables last week as my server rack has all hand made cables (with RJ-45 ends). I mean they work today (gb) but maybe miswired anyways.  Over the years have flip flopped using patch cables or hand made cables; but always using the same little LED tester.  I have learned my lesson here.
 
The house is totally wired.  IE: I have multiple runs of catXX to literally every room in the house.  (IE: like one behind each of the two nightstands in the master bedroom plus 4 going to the back of the MM center (and I do not watch TV)). 
 
BTW I did see used Fluke testers for $150 on Ebay last week.
 
The reason I asked is that I've been using what I consider a cheap tester at work (~$30 Ideal tester) which just has 4 LEDs that show the wiring from the 4 pairs. It's similar to this, but apparently they've changed it since... our doesn't show if there is a 'miswire', a 'short', etc. but just shows a green, PASS LED for each pair when the cable is good. Over the past 6 years I've never had a cable mis-read... If it says the cable is good, it works. If an LED doesn't light up it doesn't - then I proceed to clipping the ends and re-terminating to get the cable working.
 
That said, I bought a ~$89 Klien tester from Home Depot about a year ago (http://www.homedepot.com/p/Klein-Tools-VDV-Scout-Pro-Tester-Kit-VDV501-809/202520422#.Ud6VCW2DldA). I like it better just because I can test coax as well as use the numbered terminations to easily trace wiring. It can do RJ-11 too, but I've never terminated any...
 
Thank-you drvnbysound.  I go to homedepot about twice a week lately and never thought to look for a network tester there. 
 
I really should have purchased something better years ago.  I have been slowly moving towards poe devices.  That said I do have some 15 tabletop tablets of which about 1/2 are running using poe injectors and they do work. 
 
The oldest house cat5e long runs were originally installed with the RG6/siamese cables for CCTV.  Over the years switched over from using the RG6 to using baluns for power and video and those worked fine.  I never though did check for mismatches in the pairing of the wires.  I just ran them patch panel to jack, tested them with the cheap tester and connected the baluns.
 
I am lucky here that I have a Home Depot, Menards and Lowes literally close enough to park in one parking lot and walk across the street to the other hardware store.  I don't understand how they remain in business with such close proximity to each other.
 
In a bind I have purchased some networking stuff at the stores.  I purchased many of the dual plastic combo HV / LV boxes from Menards at around $10 each.  They did recently redone their DIY HA stuff; shelves and display. 
 
We have purchased a variety of cable testers over the years to maintain our multi-thousand drop network.  A variety of Microtest, Fluke, JDSU Test-Um and such.  Curiously, most of my techs tend to prefer this nice basic unit:  http://www.siemon.com/e-catalog/ECAT_GI_page.aspx?GI_ID=tt_stm-8
 
The Siemon STM-8 is small, reliable and it just works.  Your results may vary, but we have been very happy with this unit.  We have also tried the basic continuity LED testers and not had such good luck.  Of course, this unit doesn't show what VLAN you are on and such, but that capability adds quite a bit to the price!
